Description

- 9 - 8 Aug 1980

The invention relates to an apparatus for sorting sheet-like material, the sheet-like Material, such as strips of paper, stocks and checks, is examined and ineffective and ineffective sheet material is sorted.

Recently, various sheet material sorting devices have been developed and used which automatically examine the sheet material (hereinafter referred to as sheet) and sort it into first, effective and second, ineffective sheet material. One of these devices automatically counts the sheet material sheet by sheet to determine the number of sheets and at the same time expel or reject the ineffective sheet material that cannot be examined by the inspection device, for example foreign, different sheets and invalid sheets, with the effective Sheets are sorted into normal sheets, which are reusable, and dirty sheets, which are valid, but not reusable. The sheet material is stacked to 100 sheets and the stacks of standard sheets are bundled and printed.

The conventional sorting device sorts the sheet material one thousand sheets at a time, ie the sorting is carried out batchwise or discontinuously. The conventional apparatus can determine whether or not the number of sheets is sufficient, or whether or not ineffective sheets are contained in the sheet material being processed. It is impossible to determine which stack of sheets of ten stacks each containing 100 sheets is an abnormal sheet

130008/0945

or has abnormal leaves. In the case of securities, 100 sheets are stacked and using a narrow one Strips bundled, with the ten sheet stacks, which 'comprise a total of 1000 sheets, collected and with a wide strips can be bundled.

When operating the conventional device, the IQOO sheets are handled in one processing step, but the sheet stacks of which are each 1OO sheets often handled by different people. After the sheet material is processed, there is often the desire to know who is handling the stacks of standard sheets, including the non-normal sheets, handled. To meet this requirement, the sheets must contain 100 sheets instead of 1000 sheets are processed. Determining the number of sheets and processing the ineffective sheets takes place in this case one hundred sheets with the result that the downtime of the device increases, whereby the efficiency of the sorting device deteriorates considerably and the saving in labor time of the system decreased.

A sorting device has been proposed which is adapted to divide the sheets one hundred sheets at a time processed, requiring the input of a sorting card into it by an operator is. This complicates the operation for the operator. The proposal is therefore impractical.

The invention, as it is characterized in the claims, is therefore based on the object of providing a device for sorting sheet-like material which has a reduced downtime and at the same time

130008/0945

only minimally increases the work of the operator.

The object according to the invention is thus achieved by ■ that the processing of the sheet material one hundred sheets at a time is performed, with a minimal downtime between processing of each 100 sheets, whereby the operator does not have to enter the sorting card. The inventive Apparatus for sorting sheet material thus performs efficient sorting.

The device according to the invention for sorting sheet material is mainly used to handle securities such as stocks, checks and strips. The apparatus supplies the stacks of unit sheets, each containing 100 sheets, to a sheet supply means as they are arranged. The sheet delivery device reads the information which is marked on a narrow band for bundling the unit sheet stack, tears open the narrow strip and transports these sheets, sheet by sheet, to the subsequent processing station of the device. Features of the sheets are scanned during sheet transport. The sheets are sorted on the basis of these scanned features. The sorted sheets are finally bundled with some predetermined number of sheets.

Other objects and features of the invention will become apparent in connection with the description with reference to the accompanying drawings Drawing clearly. In the drawing show:

It should be noted in advance that the handling of securities such as Checks or strips through the sorting device according to the invention is described. The security that is being handled is called a sheet for the sake of simplicity.

I. First sheet:

This hand is an effective, valid hand.

a) Normal sheet:

A sheet that is judged to be normal and usable based on its test result, and that, after it has been processed by the device, reused in its field will.

b) Dirty sheet:

A sheet which is judged to be normal and reusable on the basis of its examination result and which, after it has been processed by the device, is collected on the input side and discarded.

II. Second sheet:

This sheet is invalid or invalid and is known as the reject sheet.

130008/0945

303QH4

This sheet can be an invalid sheet, an unidentifiable sheet Leaf and a strange, different leaf. The invalid sheet is considered counterfeit or invalid judged. The unidentifiable sheet cannot be examined because it has a large scratch or has several large scratches, or because it was taken out in a state where it was above you another sheet lies. The foreign leaf is a leaf that is different from the leaves that are in the device should be processed.

Of these securities to be sorted, i. H. normal Sheets, dirty sheets, and rejectable sheets become the normal sheets as a unit sheet stack with 100 sheets each stacked. The dirty leaves are cut up by a cutting device. the Rejected sheets are collected in a rejectable sheet collecting device.

The sorted and stacked normal sheets are fed to the next station as a 100-sheet stack. At this stage, the stack of 100 sheets or unitary sheets is only stacked, but not yet bundled. These stacks of standard sheets are then bundled at a suitable station. Bundling is carried out such that a bundle tape such as paper tape is wrapped around the stack of unit sheets and the outer end of the loop is attached to the outer periphery of the bundle which is wrapped around. The paper tape for bundling the unit sheet stack is called a narrow strip. The bundled unit sheet stack is transported along a transport route. In the middle of the transport path, the name of the operator, the date of processing and the like are printed on the narrow strips of the bundled stack of standard sheets

130008/0945

printed. After printing it will be the normal stacks of sheets collected. When collecting the stacks, 10 stacks are collected and bundled into a large bundle. This bundle from 10 strepel is called a large bundle.

The information that is recorded on the narrow strip for bundling the sheets when the sheets are bundled are fed to a delivery device, is read by a reading device. The information read is fed to a sorting card manufacturing device, where it is printed on the sorting card. on the sorting card will show the number of normal sheets, the number of dirty sheets and the number of sheets that have been read Information such as the operator's name, the date of processing, and the like are printed. The so produced Sorting cards are together with the rejected sheets in a facility for collecting the Rejected sheets are collected when sorting the sheets is finished.

An embodiment of the invention will now be described.

The delivery device 100 consists of a bundle delivery table IG1, a unit sheet stack delivery device 102, a strip tearing device 103 and a reading device 104. The bundle delivery table 101 holds the stacks, ie the sheet stacks P, which are bundled by narrow strips T, in a recess 105 in the upright state. The table 101 conveys one of the thus held stacks of sheets one by one in the direction of arrow A while they are held by the pins 106 attached to an endless belt (not shown) provided in the table 101. The unit sheet stack delivery device 102 is composed of a leaf spring 107 which presses the sheet P from above, and a deflector (not shown) which horizontally sets the sheet P held in an upright state and places it on the reading table 108. The strip tearing device 103 consists of a cutting device 109 for tearing open the strip T with which the stack P is bundled, as shown in FIGS Slide plate 111 which pushes the sheets P in the direction of arrow B, which are horizontally arranged by the unit sheet stacker 102. The cutter 109 pushes the sheets P upward by means of an arcuate spring 112 to separate the sheet stack P and the narrow strip T from each other, forming a larger space therebetween, and then inserts an edge (not shown) into this larger space to cut the narrow strip T. The cutting device. 109 moves horizontally back and forth in FIG. 3. The disposal device consists of a U-shaped frame 110a as well as arms Hob, the

1 30008/0945

extend vertically away from the legs of the U of the frame 110a. The frame 110a is about a pivot point 113 pivotable with the aid of an electromagnet 114. The arms 11OfcTweise each arranged opposite one another On nails that grasp the narrow strip T and lift it upwards with the help of the electromagnet 114, while they hold him ..lit her nails to the strip T from the stack of sheets P to remove. The removed narrow strip T is raised from the arms with a device removed to remove small strips (not shown). The sliding plate 111 moves in Fig. 3 in left section back and forth to move in the direction of arrow B on the nails of the arms llOb the strip of on the reading table 108 horizontally arranged sheet bundle P sent from the unit sheet stacking delivery device 102 Is delivered batch by batch. The reading table 108 is made of a transparent material. The reading device 1O4 has a lamp 115 to guide the strip T through the reading table 108 to illuminate therethrough, furthermore an image converter 116, the light emitted by the strip T emitted by the Lamp 115 is illuminated, reflected, converted into an electrical signal.

_ ₁₉ _ 3030U4

the front pile of sheets P rotated to the horizontal by the deflection device (not shown) and placed on the reading table 108. Thereafter, the slide plate 111 moves in the direction of arrow B to slide the stack of sheets P rotated in the horizontal. As a result, the narrow strip T with which the stack P is bundled is held by the arms 110b of the strip tearing device 103. Thereafter, the cutter 109 moves in the direction of arrow B. During the movement of the cutter 109, the arcuate spring 112 slides along the lower surface of the stack of sheets P to push the same up and a space between the stack of sheets P and the narrow strip T. to accomplish. Thereafter, the edge (not shown) is inserted into the space to break the narrow strip T. After the break-up, the cutting device 109 returns to the initial state. The electromagnet 114 is then actuated in order to rotate the frame 110a. This raises the arms 110b while holding the narrow strip T, so that the strip T is removed from the bundle P of sheets. The narrow strip held by the arms 110b is removed therefrom in the manner described above. Then the frame 110a is moved back to the original position. The sliding plate 111 is then moved in the direction of arrow B in order to move the stack of sheets to the removal and transport device 2OO.

When the stack of sheets P is placed on the reading table 108 , the lamp 115 is turned on at the same time to illuminate the narrow strip T. The incident light is reflected by the narrow strip T and the reflected light is picked up by the image converter 116. The imager 116 is an optical, self-scanning reader such as a CCD (charge coupled

130008/0945

device), and outputs information such as the name of the operator, the date of sheet processing and the like recorded on the narrow strip T. The read data are converted into corresponding electrical Signals converted. The electrical signals are used as read signals by the sorting card manufacturing device 10000 supplied.

The removal and transport device 200 consists of a delivery station 201, a removal station 202, a Transport station 203 and a cleaning station 204. The delivery station 201, which is connected to the delivery device 100 is provided with a sheet pressing plate 205 which moves vertically in the delivery station 201. The pressing plate 205 pushes the unit sheet stack P up while carrying it, and presses it against the Take-out station 202. The sheet pressure plate 205 is on an endless belt. 207 attached, wrapped around rollers 2Ο6 is. The pressure plate 205 moves with the rotation of the belt 207 in the vertical direction. A feather is provided at both ends of the pressure plate 205 to increase the pressure on the stack P (Fig. 3). One clear cover 209 is provided on the front of delivery station 201 and a reference surface 210 opposite of the cover 209, with the reference surface 210 the rear side of the sheet stack P from the rear of the device lasts. The reference surface 210 moves back and forth by an adjuster 211 for the Sheet type is operated. The sheet type setting device is used to set the processed in the device Leaf types used. The apparatus of this embodiment processes three kinds of sheets X, Y and Z. with different width and length. The reference surface 210 thus moves back and forth a distance that is determined by the width of the sheet P.

130008/0945

3030H4

The removal station 202 consists of a rotor 212, the rotates clockwise and a suction device (not shown) which is arranged around the rotor 212 is. The rotor 212 is driven clockwise by a drive (not shown). The suction device has a thickness that gradually decreases in the direction of rotation of the rotor 212, which has a smooth surface. A suction port (not shown) connected to a vacuum device (not shown) communicates is provided on the surface of the suction device.

The transport station 203 conveys the stack of sheets that has been removed from the removal station 202 to the Transport and sorting device 400. It consists of an inlet section 213 and a guide plate 214. The Cleaning station 204, which communicates with the vacuum device (not shown), sucks off the dust that is on the The stack of sheets P conveyed by the transport and sorting device 400 adheres, thereby causing the effects of the dust can be reduced to the examination in the subsequent examination device 300.

The operation of the removal and transport device thus constructed will now be described. First, the sheet type setting knob 211 is rotated to set the type of sheet to be processed, so that the reference surface 210 moves to adjust the width of the sheet to be processed. Under this condition, the pile of stacks of sheets supplied from the delivery device 100 is brought into position from three directions by the vertical portion on the rear side of the sheet pressing plate 205, the reference plate 210 and the pressing plate 111 .

Thereafter, the sheet stack pressing plate 205 moves

130008/0945

at the top, carrying a pile of sheet stacks P to push the sheet stacks upwards with a certain pressure to press. At the same time, the pressure plate 205 moves to the right and is in a certain position the delivery chamber 206 is set. The rotor 212 then rotates clockwise and the suction device rotates (not shown) pulls the top sheet stack P to the delivery station 201 and conveys it to the receiving station 203. The stack of sheets P that has been removed is conveyed along inlet path 213 to cleaning station 204 where it is cleaned and then to the inspection device 300 is fed.

While the stack of sheets P, which is present in the delivery station, is removed from the removal station 202, the next stack of sheets P is fed to the receiving part 100, where the information on the narrow strip T is read. When reading the narrow strip T in the delivery station 201 is finished, the sheet stack P is conveyed on the reading table 108 to the delivery station 201. Be that way the stack of sheets removed continuously.

The examination device 300 (cf. FIG. 1) consists of an optical examination station 301, a magnetic examination station 302 and a mechanical examination station 303 Light beams are processed in a suitable logic in order to determine the optical properties of the sheet stack P. The magnetic examination station 3Ο2 determines the magnetism of the sheet stack in order to determine the magnetic properties of the sheet stack P. The magnetic surveillance

130008/0945

station 302 consists of the magnetic heads 304, a pair of pressure pads 305 to press the sheet P against the magnetic heads 304, and a pair of holding rollers corresponding to the Conveyor belt gives the transport and sorting device 400 a zigzag shape. The pressure pads 305 lie in the same plane as the magnetic heads 304. The sheet stack P is in close contact with the surface of the Magnetic heads 3O4 brought in such a way that the conveyor belt of the transport and sorting device 400 moves to the pressure pad 305 with the aid of the holding rollers 3O6, the sheet stack P against the magnetic heads 304 through the pressure pad 305 is pressed. In this way, a good magnetic-electrical conversion is ensured.

The mechanical inspection station 303 determines whether or not there are foreign sheets or sheets stacked on top of one another by determining the thickness of the sheet stack P. The examination station 303 consists of a fixed reference roller 307, the circumferential surface of which does not change its position, an oscillating roller 308 in order to exert pressure on the stack of sheets P, which is moved to the reference roller 307, and a sensor 309 in order to change the position of the oscillating roller 308, for example to be recorded optically. The sensor 309 detects a change in position of the oscillating roller 308 when a sheet P that comes between the reference roller 307 and the oscillating roller 308 is thicker than a reference normal sheet. The reference roller 307 consists of a tubular part with a smooth peripheral surface. The oscillating roller 308 is formed by a group of small rollers that are opposed to the reference roller 307. The small rollers are arranged along the axis of the reference roller 307 to determine the thickness of the stack of sheets P. The sensor 3O9 has several transducers in order to detect the position changes of the oscillating roller 308, which are corresponding to the oscillating rollers 308.

130008/0945

are ordered.

The sheet inspection device 300 will now be described with reference to FIG. 4. The optical examination station 301 consists of a light source 31O for illuminating the sheet P, a light receiving part 311 that receives the light which is reflected from the sheet P, and a light transducer 312 which receives the light which the sheet transmits. The light receiving parts 311, 312 are arranged so that they the optical properties of the Record sheet P. However, they are generally represented as light receiving parts 311 and 312, and for reasons of a simplified representation. Because of this arrangement, both convert light-receiving Divide 311 and 312 the reflected and transmitted light, respectively, into corresponding electrical signals. These electric Signals are fed to amplifiers 313 and 314. The amplifiers 313 and 314 amplify the signals of the light receiving parts 311 and 312 at a certain signal level and then feed them to the integrators 315 or 316 to. After receiving the output signals (analog signals) from amplifiers 313 and 314, integrate the integrators 315, 316 for a predetermined time and then output them to signal combination circuits 317 and 318, respectively. Depending on the sheet type setting signal representing the type of sheet P to be inspected, combine the signal combination circuits 317, 318 based on the plurality of output signals of the integrators 315, 316 a given combination. The signals generated by the combination circuits 317, 318 are an analog signal Xl formed due to the light transmitted by the sheet P, the amount of contamination of the sheet P to be detected, an analog signal X2, which is formed due to the light transmitted by the sheet P, to determine whether the sheet is false or forged or not, an analog signal X3, which due to the by the

130008/0945

3030H4

Sheet P of reflected light is formed to determine the degree of contamination of the sheet P and an analog signal X4 formed based on the light reflected from the sheet P to determine whether the sheet P is false or forged or not. The signals Xl to X4 are applied to comparators 319 to 322, where with a., b, c. or d. be compared. the Reference signals a_ to d are analog signals that have a signal level that corresponds to the type of leaves to be examined P reproduces. Of these signals, the signals b and d have the predetermined widths bl. to b2_ or dl. to d2. on. The results of the comparisons of the comparators 319 to 322 become a logic decision circuit 323 supplied.

The magnetic heads 304 detect the magnetism generated from the front and rear sides of the sheet P and convert them into corresponding electrical signals. These converted electrical signals are fed to respective amplifiers 324 and 325, respectively. The amplifiers 324 and 325 amplify the signals coming from the magnetic heads 304 to certain signal levels. The amplified signals X5 and X6 are fed to comparators 326 and 327. After receiving these signals, the comparators 326 and 327 compare them with reference signals e. and f .. The reference signals e_ and £ are analog signals with levels that reflect the type of sheets to be processed, and have a predetermined width el to e2. or ü to £ 2. on. The results of the comparisons of the comparators 326 and 327 are fed to the logic decision circuit 323.

The oscillating roller 308 responds to the thickness of the sheet to be examined by changing its position vertically.

130008/0945

A change in position which exceeds a predetermined value actuates the sensor 309, whereby it is recognized that the sheets P have been taken out one above the other or that a foreign sheet is present. As a result, the sensor 309 generates a scanning signal corresponding to the change in position, which in turn is supplied to the signal combining circuit 328. The signal combining circuit responds as a kind of gate circuit to the sheet type setting signal to combine the signals from the sensor 309 in a predetermined combination and to generate the analog signal X7 representing the thickness of the sheet P. The signal X7 is fed to the comparator 329, where it is compared with a reference signal a which is an analog signal having a level which depends on the kind of the sheet P to be examined and which has a width between gX. to g2. having. In this way, the comparator 329 outputs the comparison result as a signal representing an abnormal thickness of the sheet to be inspected (for example, superimposed sheets or a foreign sheet) to the decision logic circuit 323. The reference signals a. to si are generated by a reference signal generator (not shown) in accordance with the respective sheet type setting signals. The reference signal generator can be an analog memory to selectively generate analog signals according to the sheet type setting signal, or the combination of a fixed memory, which is addressed by the sheet type setting signal, and a D / A converter for converting digital signals coming from the read-only memory into analog signals. The sheet type setting signal is generated when the sheet setting device (Fig. 1) is operated. It shows the nature of the straight from that. Processed sheet device P.

The decision circuit 323 decides on the hand P,

130008/0945

3030H4

as indicated in the table below, based on the comparison results of the comparators 319, 320, 321, 322, 326, 327 and 329.

The decision circuit 323 judges the leaves P to decide the kind of the leaves P, and generates various signals, namely a decision signal 323a, a signal 323S for a dirty sheet, a signal 323N for a normal sheet, and a total signal 323T for

130008/0945

the sum of normal and dirty leaves. The decision signal 323a is used as a transmission and classification control signal of sheets P is used. Signals 323N and "323S" for dirty and normal Sheets and the total signal 323T are each used as counting signals. The signals in question sent by deriving from the decision circuit 323 are fed to the controller (FIG. 10), which will be described below will.

Transfer and classification

The transmission and classification device 400 (FIG. 1) essentially consists of a first transport path 401, a second transport path 402 and a third transport path 403. The transport paths 401, 402 and 403 each have drive or follow-up rollers 404 and conveyor belts 405, which are arranged around the rollers 404. The transported sheet P is gripped by the surfaces of the conveyor belts 405 which are opposed to each other, thereby being fed to the next stage. The first transport path 401 extends through the sheet receiving station 302, the sheet cleaning station 204 and the sheet inspection device 300. The second transport path 402 is provided with a first guide part or gate 406 at its branching point. The first gate 406 is configured to pivot when operated by a rotatable solenoid (not shown). It guides the sheet P, which comes from the sheet inspection device 300, to the second transport path 402 or the third transport path 403 as a function of the decision signal 323a (FIG. 4). A detector, for example an optical detector, is arranged in front of the first classification gate 406 . The detector 407 detects the sheet that has passed through the first transport path 401.

The end section of the second transport path 402 is arranged above the sheet delivery station 201. At the end section a stacking station 800 is provided for the rejected sheets, which has a guide plate 801, which is coupled to the end section of the second transport path 402, a box 802 for stacking the rejected Sheets P falling down, guided by the guide plate 801, and has a door 803 to the front Opening of the sheet stacking box 802 to open and close. The third transport route 403 consists of the transport route 403a for normal sheets and the transport path 403b for dirty sheets. At the branching point A second classification gate 408 is provided for the two transport routes 403a and 403b. The second classification gate 408, which is constructed like the first classification gate 406, responds to the decision signal 323a (Fig. 4) to the sheet P coming from the inspection device 300, the transport route 403a for the normal Sheets or the transport path 403b for the dirty sheets to be fed. Before. the second classification gate 408, a detector, for example an optical detector 409, is also arranged. The detector 409 detects the sheet that passes the third transport path to generate a measurement signal. When a measurement signal is generated is, the second classification gate 408 is pivoted. The normal sheet transport route 403a extends up to a unit stacker 500 for normal sheets. An optical detector, for example the detector 410 is provided on the sheet entry side of the unit sheet stacker 500. The transport

The detector 410 represents the passage of the sheet P, and the timing of the sheet being transported to be picked up. The roller 404 and the conveyor belt 405 form part of the transport path 403a for the normal sheets. The facility 500 for education A unitary stack of normal sheets is supported by support plates 506 which are placed on a frame 505 are. The separating device 502 consists of a drive roller 508 '(not shown) which is attached to the shaft 507, which is carried by the support plate 506, with running rollers 509 which are supported by angles (not shown), a separating lever 510, which forms a gap with the drive roller 508 and the following Rollers 509. The shaft 507 is rotatable and has a motor (not shown) which sets it in rotation, tied together. Grooves (not shown) through which the separating lever 510 is fixedly arranged are on the outer peripheral surface of the drive roller 508 is formed. In a similar way, there are grooves on the outer circumferential surface of the concurrent ones Rollers 509 are provided. The aforementioned angles (not shown) are made by shaft 507

130008/0945

hold, the angles being rotatable about the shaft 507. A shaft 511 extends between angles and rotatably supports the lower idler roller 509. Above the shaft 511, a shaft 512 extends between the angles. A curved leaf spring 513 is rotatably arranged on the shaft 512. Shafts 514 and 515 are on both Ends of the leaf spring 513 attached. The upper right idler roller 509 is rotatably mounted on the shaft 514, and the upper left idler roller 509 on the shaft 515. As a result, the angles or claws (not shown) and the leaf spring 513 rotatable and the upper idler rollers 509 opposite the drive roller 508 and the lower revolving roller 509 can be pivoted. the Claws or brackets that support rollers 508 and 509 are normally open to frame 505 by a coil spring (not shown) charged. Furthermore, a pawl (not shown) is screwed onto the angle. The pawl is in engagement with an anchor (not shown) by the attraction and release of a Electromagnet (not shown) is moved when the angle is counterclockwise against the voltage of the Spring (not shown) can be moved.

The separation levers 510 in the form of metal rods are curved at one end. The separation levers 510 are on the front and provided with stop pins 516 and 517 at the rear end. The stop pins 516 and 517 define the range of motion of the separating levers 510. The stop pins 516 and 517 are fastened with fasteners 518.

The device for forming the stacks of standard sheets includes: sliding stops 519 on the relevant Sidewalls, a clear plate that covers the front of the unit sheet stacker 503

The striking part 523, which is attached to the housing 529, serves to hit the sheet P entering through the transport roller 501 to make it fall. That Striker 525 is coupled to a rotatable electromagnet (not shown). The striking part 523 is pivoted with a certain number of strokes by the electromagnet at high speed. The reference numbers 530 and 531 represent guide members that guide the entering sheet P while being at the top of the slide stopper 519 are attached. The slide stop 519 and the striking part 523 are telescopic in the housing 529 arranged. The guide members 530 and 531 move in the X direction with the movement of the slide stops 519. The holding part 524 has an inverted L shape. The horizontal part of the inverted L is in three Parts shared. The sheets P are stacked on the holding part 524 disposed below the separator 510, moving it up and down if necessary.

The operation of the device for forming uniform stacks of sheets, the structure of which is described in detail above, will now be explained. The sheet P entering through the sheet entry port is first guided by the guide members 530 and 531 and then struck by the striking member 523 to fall, so that the sheets P are successively stacked on the separator 502, which are in the means 503 for forming uniform sheet stack is arranged. When approximately the predetermined number of sheets P are stacked on the separator 502, the separator 502 retreats in the direction of arrow E. The motor (not shown) sets the drive rollers 508 in rotation so that the separating lever 510 moves to the left, or in the direction of arrow E.

130008/0945

in Fig. 5. After the separation lever 510 has retreated, the sheets P that have been stacked in the separation device drop due to their weight on the holding plate 524 which has been raised to a position shown in solid lines and which is used to pick up the falling leaves. At this point in time, the separating device 502, which has withdrawn in the direction of arrow E, is pivoted counterclockwise while changing its angle of rotation, i.e. in the direction of arrow E. It then moves in the direction of arrow G and pulls itself into a position (Fig . 5), which is indicated by a line with two dots, where it is in the ready position. The separating lever 510 then moves in the direction of arrow E and the stop pin 516, which is arranged at the end, comes into contact with the follower 518, while the separating lever 510 is pivoted in the direction of arrow F. This pivoting movement is stopped around the lever 510 when the pawl engages the anchor. After locking the separating lever 51O, the drive roller 508 rotates so that the separating arm 510 moves in the direction of arrow G. Then, when the stop pin comes into engagement with the driver 518, the rotation of the drive roller 508 is stopped.

When the sheets are stacked on the holder 524 by about the predetermined number (e.g. 100) in this way, the holder 524 moves down to the position (FIG. 5) indicated by a line with a dot . Then, when the predetermined number of sheets P is stacked on the holding part 524, the separating device, which was located above the station 503 for the formation of uniform sheet stacks in the ready position, rotates clockwise, ie in the direction of arrow H, to stand in one position stay that

130008/0945

_ 37 - 30301A4

is indicated by a solid line. If the lOO. Sheet P has been detected by detector 410, the control device shown in Fig. 10 receives a measurement signal "from the detector 410 to the electromagnet to supply a drive signal so that the engagement of the armature and the pawl is released. The separation lever 510 is released and the tension of the spring causes the separation lever 510 to drop (rotate). The sheets P on the holding part 524 are completely of the subsequently transported sheets P through the separating device 502 separated. The number of the sheets P stacked on the holding member 524 becomes that shown in FIG Control device counted on the basis of the output signals of the detector 410. Whether these sheets P in a given Number to be separated or not is checked optically by detectors 532, 533 (Fig. 5). With others Words, when the detector 532 detects the 101st sheet P if the detector 533 changes from "dark" to "light" has, it is assumed that the sheets P have been separated exactly in accordance with the predetermined number of sheets. The holding plate 524 moves from the position indicated by the one-dot line to the position (Fig. 5), which is indicated by the two-point line, while it is a predetermined number of stacked sheets P carries. This stack of sheets is referred to as the unit sheet stack. The standard sheet stack is then transferred to the rotatable rollers of the device 600 for bundling the stacks of unit sheets (Fig. 1). After the stack of standard sheets has been transported, the holding plate 524 moves up again into the position which is represented by a solid line (Fig. 3).

The guide wall 609 and the feed arm 610 are in three parts and are telescopically related to each other.

The device 603 for looping and bundling unwinds the free end of the band for bundling from a supply of band with the required number of turns in order to form a loop of the bundling band. The free end of the ribbon hangs in the loop so that the space in the loop is divided into two parts. In the bundle or bundle loop, the unit sheet stack Pl is through the device 602 for. Transport of the unit sheet is moved in, whereby the loop is pulled apart to bundle the unit sheet. The bundle loop formation device 603 is provided on the left side (FIG. 7) of the sheet bundle transport device 602. The bundle tape wound around a drum 620 of the tape delivery device is, for example, a green tape 621 made of paper (a yellow tape is used to bundle the soiled unit stacks), and is fed to the tape feed path 623 via a tape guide roller 622. In the middle of the guide route

623, the paper tape 621 enters the nip of the tape feed rollers 624 and 625, and is thereby advanced. The guide track 623 and the guide rollers

A pillow stop 632 for stopping the glue pad 628 is provided on a roller support table 626 in front of the cutting device 631. Above the roller support table 626, an arcuate nip roller drive lever 634 is provided, which, if necessary, rotates about an axis of rotation 633 in the direction of the arrow N. A roller lever 635, which at the end of the roller drive lever 634 is rotatably mounted, is pivotable in a certain range. Furthermore is a rotatable squeegee roller 636 is provided at one end of the lever 635. The squeegee roller 636 presses one end of the Glued and cut tape against the part of the tape that is wrapped around the stack of sheets Pl.

At the front portion of the roller holder 626 or on the right-hand side in FIG. 6, a tape guide part 637 is provided, into which the front end of the tape 621, which comes from the delivery rollers 624 and 625, is inserted with a certain length. A pair of unit sheet stacking guides 638, which are provided in parallel on both sides of the guide member 637, serve to:

130008/0945

the unit sheet stack P1 moved by the feed arm 610 will lead. The guide members 637, 638 are attached to a guide member drive pulley 649 and run around in the direction of the arrow Q or, if necessary, are removed from the discs in the direction of the arrow R. 649 moves. A pair of staple drive levers 639 are such above guide members 637 and 638 (Fig. 7) arranged so that they converge substantially to the left. At the end of the lever 639 are pairs of clamp bars 640, 641 arranged parallel to one another at certain intervals. The levers 639, which are attached to the rear or 7, the left end are connected to the drive part · 642, are in the direction of the arrow S through the drive part 642 open and closed if necessary. When closing the unit sheet stack Pl, the is moved by the feed arm 610, clamped by the clamp rod pairs 640, 641.

In Figs. 6 and 7, reference numeral 643 denotes a tape insertion prevention plate, and it shows the shape an inverted U. The prevention plate 643 is at the portion that the ends of the sheet guide members 638 corresponds, essentially perpendicular. The reference numeral 644 in Figs. 6 and 7 denotes the base of Contraption. A portion 645 enclosed by a two-point line means a part in which the corresponding parts 621 to 636 are arranged.

The operation of the device 600 for bundling the unit stacks from normal sheets will now be described. The rollers 601 normally stand still when the mounting plate 605 and the clamp 606 are directed upwards to receive the unit sheet stack P1. To this At this point, the clamps m6O6 are closed. Under this

130008/0945

Condition, the bracket 606 corresponding to the holding part 524 opens to receive a stack of sheets, as shown in Fig. 5, if the holding part 524 carrying a unit sheet stack (e.g. 100 stacked sheets) moves downward. The holding part 524 moves further downward and temporarily stops when the horizontal section of the holding part 524 with the rotatable rollers 601 is telescoped. In this way, the stack of unit sheets P1 on the holding member 524 is transferred onto the outer peripheral surfaces of the rotatable rollers 601. When the stack of unit sheets Pl has been transferred to the rotatable roller 601, the clamp 606 is closed to clamp the stack of unit sheets Pl and the rollers 601 start rotating in the direction of arrow J while the holding member moves upward. When the rotatable rollers 606 have rotated approximately 90 ° clockwise, then they stop temporarily and the clamp 606 opens again. At this time, the lower side of the unit sheet stack P1 opposite to the bottom plate 614 is substantially horizontal. The unit sheet stack P1 is transferred onto the bottom plate 614 with the sheets arranged substantially vertically. In this way, the unit sheet stack Pl removed from the holding member 524 when it is arranged substantially horizontally is rotated by about 90 in the direction of arrow J to be arranged substantially vertically. The rotatable rollers 601 then stop rotating and the clamp 606 opens. Thereafter, the drive 613 is actuated, with the result that the slide 607 moves forward in the direction of the arrow L to move the stack of unit sheets on the fixed bottom plate 614 to come into contact with the guide wall 609. The slide 607 remains temporarily in this position. The pushed standard sheet stack Pl is thus open

130008/0945

3030HA

of the movable floor plate 615 is arranged substantially as shown in FIG.

When the pusher 607 stops momentarily (or when the pusher 607 begins to move forward), the wrapping and bundling device 603 begins to form the bundle loop. The structure and operation of the wrapping and bundling device 603 will now be described with reference to FIGS. 8A to 8J. Usually, the roller holders 626, the glue pad 628, the squeegee roller 636, the tape guide part 637, the unit sheet stack guide parts 638, the staple bars 640, 641 in the state shown in FIG. 8 or FIGS. 6 and 7 stand still and stand for ready for operation. When the bundle looping command is given in this state, the reel rotator 626 rotates clockwise as shown in FIG. When the roller holder 626 stops, the delivery rollers 624, 625 rotate in the tape transport direction, so that the tape 621 is advanced and the leading end of the tape is inserted into the guide member 637 with a certain length, as shown in FIG. When the leading end of the strip is inserted into the belt guide part 637, the roll rotator rotates 626 in Gegenuhr2eigersinn, as shown in Fig. 8, to return to the starting position, and the delivery rolls 624, 625 rotate again to the tape 621 supplied . At this time, the disk rotates in the direction of arrow Q while the tape guide member 637 and the unit sheet stacking guides 638 rotate at the same time. Then, when the guide parts 637, 638 are arranged substantially vertically, the rotation and thus the supply of the tape 621 is stopped. As described above, there is one end of the tape

130008/0945

3030U4

621, which is delivered by the delivery rollers 624, 625, wound in about two turns, as shown in Figure 8, with the leading end 621a of the tape in the space formed by the loop so that the space is divided into two parts. After the belt loop has been previously formed in this way, the loop awaits the unit sheet stack Pl, which is from the arm 610 is fed. The bundle loop 646 becomes on the right side of the tape insertion preventive plate 643 as shown in FIG.

When the bundle loop 646 has been formed, the separating plate 608 is pivoted downward via the axis of rotation 617. At this time, the partition plate 608 is in the middle of the thickness of the unit sheet stack Pl, the is arranged substantially vertically on the movable base plate 615, inserted so that the unit sheet stack PI is divided into two parts by the partition plate 608. When the stack is split, the pusher pulls

607 back a distance equal to the thickness of the partition plate

608, whereby the insertion of the partition plate 608 into the unit sheet stack P1 is facilitated. the Partition plate 608 stops temporarily when it has been inserted into the unit sheet stack P1. If the Separation plate 608 stops in the unit sheet stack Pl, the feed arm 610 moves in the direction of the arrow M forward and transports the divided stack of unit sheets Pl on the movable platen 615 while the same carries it along the guide wall 609 in the direction of arrow M. At this point, the slide pulls 607 (it moves to the right in Fig. 6) to return to its starting position and stop there. At this point the rotatable rollers .601 close the clamp 606 in order to obtain the next unit

130008/0945

to save stacks of sheets and to turn by 90 °, whereupon the above operation is repeated. In this way, the divided unit sheet stack Pl, which is transported by the Zttführarm 61O (Fig. 7), guided by the unit sheet stacking guide part 638 and the left part in Fig. 7 is stopped at the position in which it is inserted into the bundle loop 646 as shown in Figs. The tape guide part 637 is inserted between the parts of the divided sheet stack in this state, as shown in FIG. To this At this point, the partition plate 608 is pivoted upward to withdraw from the unit sheet stack Pl to return to the starting position and stop there.

When the unit sheet stack P1 is inserted at the front end into the bundle loop 646 and the partition plate 608 has returned to the original position, the guide parts 637 and the unit sheet stack guide parts 638 retract (they move to the left in Fig. 7), namely together with the pulley 645, and it moves into the drive section 642 in Fig. 7. At this time, the tape anti-pulling plate prevents the bundle loop 646 and the guide members 637, 638 from being drawn in. The free end 621a of the band, which hangs in the interior of the bundle loop 646, is arranged between the first and the second part of the divided sheet stack (cf. a closing operation so that the unit sheet stack Pl is clamped by the clamp bars 640, 641. The leading end 621a of the tape is thereby inserted into the unit sheet stack P1 as shown in FIG. At this point in time, the

130008/0945

guide arm 610 back, or he moves to the right to return to its starting position and there linger. When the unit sheet stack from the clamp bars 640, 641 is clamped, the delivery rollers 625 rotate in the opposite direction to the direction in which the delivery rollers 624 and 625 transport the tape so that the tape 621 is withdrawn around the bundle loop 646 as shown in FIG. After loop 646 is finished tightening, it rotates Lever 627 counterclockwise, as does the glue pad 628, as shown in FIG. 8, so that the tape 621 is attached to the Pillow carrier 632 is provided with glue. After the tape has been glued, the glue pad 628 returns to its original position return.

When the tape 621 has finished gluing, the lever 634 rotates clockwise and the nip roller 636 moves as shown in Fig. 8 so that the roller 636 comes into contact with the corner of the stack of unit sheets to butt the tape 621. At this point the cutter will 631 operated to cut the tape 621. Then the nip rollers 636 are down onto the The tape wound around the unit sheet stack Pl is rotated by rotating the lever 634, wherein press them onto the tape. As a result of this rotation of the nip roller 636, the end of the tape is provided with glue and which is cut off is attached to the tape wound around the unit sheet stack P1, the tape is forcibly pressed. In this way, the unit sheet stack P2 bundled with the belt 621 is obtained. The unit sheet stack in this state is referred to as a bundled unit sheet stack P2. When the gluing and the squeezing process by the squeezing rollers 636 is finished, the movable base plate 615 (Fig. 7), as indicated by a line with two dots, and

130008/0945

levers 639 also open. After that, the clamp is bundled with the clamp bars 640 for the Unit sheet stack P2 is opened and the bundled unit sheet stack P2 falls freely and becomes the device Classification of the bundled stacks of unit sheets placed under the bundling device. When the bundled unit sheet stack P2 falls to the classifier 400, the nip roller moves 636 back to the starting position, as shown in Fig. 8, and the guide parts 637, 638, which are in the drive part 642 will move forward to return to the position shown in FIG. the Disk 649 then rotates again in the direction of arrow Q and the corresponding guide parts 637, 638 rotate also, as shown in Fig. 8, back to the starting position in which they are for the next bundle looping process be available.

During the removal of the bundled sheet stack or the bundled unit sheet stack P2 along a removal path 650, a printer (not shown) prints the operator's name and the date of sheet processing on the strip (portion of the tape used for wrapping 621). After printing, the bundles Sheet stack bundling device, which is arranged separately in front of the sorting device, the sheet stacks in 10 sheet stacks .

130008/0945

It is readily apparent that any means for invalidation in the sorting machine of the present invention can be used for sheet material, provided that it certainly invalidates the soiled sheet. For example the soiled sheet can be chemically melted or burned to invalidate it.

A detector 411 detects the soiled sheets that are sorted here by the second sorting gate 408 to count them to determine the number of dirty sheets sorted by the second sort gate 408 will. The device 800 collects the sheets to be rejected, as described above, belonging to the second Transport route 402 are performed.

An operating part 900 consists of a console 901 which is provided on the sorting device and a control panel or a keyboard 902 which is provided on the console 901. The keyboard 902 is provided with a display 903 for the total number, a display 904 for the number of sheets to be rejected, ten keys 905 and a switch for switching on or main switch 906. The total number display 903 displays the total number of stained and normal sheets of each unit sheet stack. The display 904 shows the number of sheets of the unit sheet stack to be rejected, which is obtained by subtracting the total number from 100. The ten keys 905 are used to input the required information to the control device described below. The main switch 906 is used to start up the sorting device. After the switch 906 has been actuated, the delivery device 100 is put into operation in order to deliver bundled sheet stacks P as sheet-like material to be sorted.

The device 1000 produces the sorting card in accordance with the read signal of the reading device 104 and the printing information that comes from the control device. In the sorting card production part 100O, a heat-sensitive paper 1001 is sorted via a transport path 1004 and rollers 1002 and a belt 1003. In the middle of the transport path 1004, the required imprint is made with a heatable or heated head 1005 in order to produce the sorting card. A drive and press roller 1006 presses the heat-sensitive sheet 1001 against the heated head 1005. The cutter 1007 cuts the printed heat-sensitive sheet with a certain length. The transport path 1004 extends above the end of the end section of the second transport path 402 and serves to transfer the produced sorting card from the upper part of the collecting box 802. A guide part 801 consists of a pair of spaced rod-shaped parts. The width of the sorting card 1008 is less than the distance between these rod-shaped parts. The rod-shaped parts therefore do not impair the reception of the sorting card 1008. When the stack P is put on the reading table 108, the delivery device 100 reads the name of an operator, the date of sheet processing, and the like by a reading device 104 . The data read by the reading device 104 are supplied to the heated head 105. The heated head 105 presses on the heat-sensitive sheet 101 the information read by the reader 104 from the strip T and the result of sorting the stack of sheets of which the information has been read, for example, the number of sheets of dirt and the number of sheets Number of normal leaves. The heat-sensitive sheet 1001 is then transported by a roller 1002 and from the cutting device

130008/0945

3030H4

tion 1007 cut into pieces of a certain length. These parts are issued as sorting cards 1008. The sorting cards 1008 become a collection facility Transported over the transport route 1004 and collected together with the sheets to be rejected.

The timing is such that the sorting card 1008 in the collecting station 802 is collected when sorting the stack of sheets with which the produced sorting card 1008 corresponds, with the sheets to be rejected in the sheet stack in the collecting device 802 are collected on the sheets to be rejected. Therefore, every 100 sheets will be for sure found that the sheets to be rejected are below the sorting card but above the other sorting cards 1008 refer to the sorting cards 108. It should be noted in this context that it is not necessary to stop the operation to stop the sorter even if the information of the sheets to be rejected is 100 sheets is calculated and recorded.
